The 316L Stainless Steel Medical Mandrel is engineered for precision liner molding, tube extrusion, and thermoplastic heat setting in the manufacture of advanced medical devices such as catheters, microtubes, and multilumen shafts.
Manufactured from biocompatible 316L medical-grade stainless steel, each mandrel undergoes precision centerless grinding, followed by mirror polishing and electropolishing, achieving an ultra-smooth surface roughness <0.1 μm. This minimizes friction and ensures clean, residue-free release during liner forming or tube shaping.
With tight outer diameter tolerance (±0.005 mm) and burr-free end processing, this mandrel is ideal for cleanroom production, offering consistent performance in OEM catheter extrusion, balloon tubing shaping, and liner forming tools.
